,i My invention relates to masking machines `shown generally in my co-pendingl applica- Y tion Serial No. 314,300. Anfobject of the Apresent invention is tok simplifyfthemas'kingmachine shown in said application.

Another object is to provide means for Y bringing each of the masks comprised in the machine into contact with an object being masked,by lever means Operating independently uponeach mask. Y

' A further object is to provide means for bringing amask down on top of an 'Object being masked, and to move the mask out` of the path of the object so that the latter may be removed from the machine when liinished.

Still other objects reside in details of construction `and in novel combinations' and arrangements of parts, which will more fully ap ear` in the courseV ofthe following descrlption. e I y l In the drawings, like'y reference characters designate similar `parts in the several views. 4 Y v f Figure 1 is a side elevationof a machine embodying the features of the present invention. V, i Figure 2 is an endV elevation of themachine' shown in` Figure 1, lookingin the Figure 3 is a broken section taken along the lower part of the line 3f3 of yFigure 2.

Figure 4 is a broken section taken .on the line 4-.4of Figure 2. f

vReferring more specifically to the drawings, the reference numerals 5 designate shoes in which feet 6 of the machine rest. The feet support a rectangular, flanged base plate 7 upon which legs 8 are mounted for the support of a bed 9 for' an object to be masked, such as a box.

- Bolted to the under-side of the base plate 7 and projecting from the middle portions,

ofV the four sidesare pairs of arms 12 held rigidly together` by bolts 13V and spacing vatrt'he ends of the arms 12. Levers V15 at the ends of the machinejare fulcrumed, as shown at 16, and levers 17 at the sides of the machine are fulcrumed as shown at 18. The

- All of the springs comprised in this inven-- sleeves 14 on the bolt andV between the arms.

Pairs of upstanding levers are fulcrumed l p Y* 1 "Extendingbetween the bed 9 'and the'base v plat-e7 is an upright'jshaft 4311ponC whichlisf V,mounted va slidingv sleeve 44. An operatingV lever 48fo'r` the-"machine'has ahandle 4,5andfI mi' Y Pairs of levers 15 'are vheld together'byase-` ries of bolts 19 in spacingfsleeves '20', and

the klevers 17 areheld together by a series of bolts 21 inspacing sleeves 221. Y

The end levers 15 carry springs `23 theirnpper vendsv for the support of end masks 24. All of the masks mentioned in this specification are cupped on the side facing the object being masked, so that any ornament or inequality in the middle portion: 60 of any of the faces of the masked obj ect will on said faces. e

l The springs 23 are mounted at the'ends ofthe levers. 15 through the intermediary65 of bolts 25 ythat extend through apertured not interfere With the snugvit of the masks lplates 26 at either sideof the levers and through cups 27 for the ends o-f'fzthe springs 23. 1 i

. e n so The springs 31 arefastened to the `levers 1:7

at a short distance from the upper ends thereof. Fulcrumed at the ends of the levers 17 by means of bolts 33are pairsv of levers34 whichk carry springsV 35. At thel outer ends of the springs 35 are mountedmasks 36fforthc top of the boX. The-box to be masked is indicated linFigures 1 and2 in ldottedlines as shown at 37.111 i; f.

The springs 35 are fastened .at oneendof 90 the levers 34 by bolts38, apertured-plates 39 d and cups 40, as hereinbefore described in con'- f nection with vthe other springs. Bolts41 and. spacingV sleeves 42 are employed for holding each other.

thellevers'v 34 ri, 1jidlyiinspaced relationto@ a yoke 46 pivotally connected with sleeve 44 at opposite sides by bolts 47. The end ot' the lever opposite to the handle 45 is ulcrumed' at 50 on a support 49 pivot-ally suspended 53 on the sliding sleeve 44. The pivotal con-' nections between the links 52 and .53 are bolts 54.v These bolts also' pivotallyi connect the links 53 with links 55 on the levers l5. `The links 53 and 55 form toggles for the" lateral movement ot the levers l5.

Supports 56 are mounted at themiddle of V the sides of the base. plate 7. Levers 57' on the supports fare` pivotally connected at one end to-rods 58 which in turn are pivotally connected withy the levers 34. The other endof 0thev levers57 arie connected with links l59 on the sliding sleeve 44. The side levers I7 are connected with. the links 59' by intermediary links 60.

The operation of. the mach ine is'as follows: 25,'By raising.theroperating lever 48 to its'extreme upward position, the masks are drawn outward. A box or other object mayV then be placed in the bed 9. By lowering the lever 48, the masks are. moved into contact with the box. The springs resiliently hold the masks in position and takenp-'any play and absorb minor mal-adjustments of the ma. chine. '1 Y The up and down movement of the lever -4.8 moves the-sliding sleeve 44 concurrently. The links 53 and59 are suspendedfrom said sleeve. The linksx53 operatethe end levers 15 through the links 55, andthe links 59015- erate the sidelevers 17 through the links 60 andthe topA .lever-S134 through the levers 57 andy rods '58., V

Changes may be'made in the details ofV construction and arrangement without depart ingptrom the spirit of the invention.

That I claim and desire to secure by Letters Patent is:

l. In a masking machine, a bed tor an object to'be masked, a lever,a second lever fulcrumed; on said' lever, masks on the levers, and operating means connected to move the levers to a position inwhich the masks thereon contact with an object in the bed.
